Paidar Company, Chicago, Ill., a corporation of Illinois Filed Jan. 30, 1961, Ser. No. 85,829 9 Claims. (Cl. 297-422) The present invention relates to an improved arm assembly for a chair and particularly to a structure for mounting at the side of the frame of a barber chair or the like which provides adequate strength and proper appearance for an armrest structure.

In a mechanical chair structure such as that used for barber chairs unique demands are placed on the side armrest. The mechanical chair is provided with individual elements which are relatively movable such as the back and footrest and the chair itself usually has elevating and rotating movements. The armrests must be adequate to serve various functions in addition to being used as armrests for the chair occupant. The armrests are called upon to act as convenient members used by the barber for swinging the chair in rotation and in this use must be able to withstand the application of substantial horizontal forces. The armrests must be sufliciently strong for pushing an unattached chair assembly across a floor area or for lifting the chair. The rests are used for supporting a board for childrens haircuts. The armrests are often further provided with appurtenances such as ash trays, towel racks and other attachments which add to their need for rigidity in all directions. It is also necessary that barber chair armrests meet basic requirements for sanitation and safety.

An object of the invention is to provide an improved armrest assembly which can be conveniently and rigidly attached to the side of a barber chair framework and which provides adequate strength to withstand stresses in all directions.

A further object of the invention is to provide an improved chair armrest assembly which is of simplified construction and lightweight and is easy to manufacture and assemble and to attach and detach from a chair.

A further object of the invention is to provide an improved side arm assembly for mechanical chairs 'which is attached to the frame and independently supports an armrest and provides a finished housed and protected framework which is sanitary and safe.

Other objects and advantages will become more apparent with the teaching of the principles of the invention in connection with the disclosure of the preferred embodiments thereof in the specification, claims and drawings in which:

FIGURE 1 is a perspective view of a barber chair incorporating an armrest assembly constructed in accordance with the principles of the present invention;

FIGURE 2 is a perspective view of the armrest assembly shown as removed from the chair;

FIGURE 3 is an exploded view showing the parts used for the armrest assembly; and

FIGURE 4 is a perspective view of the framework of the chair to which the armrest assembly is attached.

As shown on the drawings:

FIGURE 1 illustrates a barber chair having a seat 11 with side armrests 12 and 13 which are mounted on the frame and are substantially independent of the seat 11 and the back 14 and footrest 15. The back and foot rest are independently movable between the positions shown and reclining positions wherein the backrest is tilted rearwardly and the footrest is elevated. The chair is supported on a columnar base 16 which connects directly to a chair frame 17 which is shown in FIGURE 4.

The frame 17 includes a plate 18 which supports the chair seat 11. Beneath the plate 18 are channels 1) and 20 for pivotally supporting the footrest 15 and for pivotally supporting vertical arms 21 and 22 that carry the backrest 14. The backrest arms 21 and 22 are tied to the footrest for simultaneous pivotal movement by connecting rods 23 and 24. v

Rigidly mounted beneath the plate 18 are yokes 25 and 26 and the ends of the yokes and the sides of the plate 18 provide rigid attachment points for the chair armrests. The plate 18 has holes 27 drilled at each side and the yokes have holes 28 drilled at each end for conveniently bolting the armrests thereto. This permits a direct transmission of all forces applied to the armrest to the chair framework 17.

The armrest assembly 12 is shown assembled and detached from the chair framework in FIGURE 2 and is shown disassembled in exploded view in FIGURE 3. Principally the assembly includes a vertical column member 29 mounted to extend upright from a base member 30. At the upper end of the column member is an armrest member 3 1. A side panel 32 covers and decoratively protects the base member 30 and a shroud 33 surrounds and decoratively protects the column member 29 and is clamped against the outer side of the base panel 32.

As shown in FIGURE 3, the column 29 includes a pair of parallel vertical bars 35 and 36 formed of channels which face outwardly so that their flat planar surface faces inwardly. At the upper end of the bars 35 and 36 is a flat rectangular elongated horizontal plate 37 for mounting the armrest 31. The armrest includes a wooden arm block 38 covered with a suitable upholstering material preferably in the form of a ribbed plastic. The plastic is tacked to the wood block and a front end cap 40 is placed on the front end of the armrest and a rear end cap 41' is placed on the opposite end of the armrest. The front end cap is held in place by a vertical bolt 42 extending upwardly through the armrest and the 'rear end cap 41 is suitably held in place such as by screws 43 turned up into the wood armrest.

The armrest is provided with a longitudinally extending recess 46 in its lower surface for receiving the rectangular plate 37, and a bolt 44 extends upwardly through the plate into the armrest and a bolt 45 extends downwardly through the armrest and is threaded into a plate thereby holding the armrest block 38 at the top of the column. The plate 37 is suitably rigidly attached at the.

upper end of the bars 35 and 36 such as by welding.

The base 30' provides a rigid mounting member for supporting the column 29 on the chair framework and includes horizontal mounting bars 47 and 48 formed of angle members which have their open sides facing downwardly and inwardly so that their upper flanges are conveniently attachable to the chair framework. The upper mounting bar has holes 47a and the lower mounting bar has mounting holes 48a which receive bolts which respectively pass through the holes 27 and 28, FIGURE 4, at the sides of the plate 18 and the yokes 25 and 26.

The mounting bars 47 and 48, FIGURE 3, are ver- 1 tically spaced and between them extend vertical spacer bars 49 and 50 which are formed of channels facing inwardly so that their outer fiat faces are facing outwardly to be parallel to the faces of the vertical bars 35 and 36 of the column 29. The vertical bars 49 are suitably attached as by Welding at their ends to the mounting bars 47 and 48.

The base 30 is protectively and decoratively reinforced and covered by the base panel 32 which includes a planar thin plate 5 1 of metal or plywood, having cleats 52 and 53 at the end. The plate 51 is of a length so that the cleats are positioned outwardly of the ends of the bars 47 and 48, as is illustrated in FIGURE 2. An opening 54 is provided through the center of the plate 51 for receiving the lower end of an operating crank arm 55, FIGURE 1. A name plate 56 is conveniently attached to the outer surface at one end of the panel 32. The panel and the end cleats are suitably covered with a decorative material or otherwise finished. The side panel 32 is connected to the base 30 by bolts 51a which pass through suitable holes in the bars 47 and 43 to turn into threaded openings or fittings in the plate 51.

The column 29 is protected and reinforced in a decorative manner by the shroud 33 which extends from the arm-rest 31 down to the base 36 and is positioned outwardly of the base to clamp the base panel 32 against the base. The shroud 33 includes a shroud body 58 with inner and outer panels 59 and 66 secured at their edges to separating blocks 61 and 62. The shroud body is in assembly slid upwardly over the column 29. The unit is then bolted together as will be described and an outer trim panel 63 is held over. the outer panel 60 of the shroud. The trim panel is held in place by a retaining edging 64 which is conveniently formed of a material such as an aluminum extrusion and has a flange 64a which extends over the trim panel and a flange 64b which extends below the shroud 58 and over the blocks 61 and 62 so that screws can be turned through openings in the retaining edging and into the blocks to hold the trim panel in place.

Openings 59a, 60a and 63a are provided in the shroud and trim panel to be in alignment with the opening 54 for the crank 55, and an escutcheon plate 55a, FIGURE 1, is placed over the outside of the trim panel to decorate the opening 63a.

The column 29 is secured against the outer surface of the base 30 by bolts 66 which project through openings 67 in the vertical bars 49 and 50, through openings 68 in the base panel, and through openings 69 in the shroud. The bolts pass through openings 70 in the bars 35 and S6 of the column and the column bars thus are clamped securely to the base with the panel 59 and the plate 51 therebetween. These panels may be formed of a somewhat resilient material such as wood which allow tightening nuts on the bolts 66 to hold the unit secure and yet prevent sqeaking noise therebetween as a result of wear. Spacer sleeves 71 may be positioned over the bolts 66 to separate the panels 59 and 60 and prevent collapse of the shroud 53.

Thus it will be seen that I have provided an improved arm structure assembly which meets the objectives and advantages above set forth. The assembly is particularly well suited to transmit forces applied to the armrest to the chair framework for moving or rotating the chair and the structural parts are enclosed to provide, a sanitary armrest preventing foreign articles such as hair from lodging between parts. The frame is made solely of horizontal and vertical parts with the surfaces and parts arranged, so that they will not catch materials that fall downwardly, and for optimum strength.

The arm illustrated in FIGURES 2 and 3 has the side opening for the control crank and it will be understood that this opening is not present at the other side of the chair.

The drawings and specification present a detailed disclosure of the preferred embodiments of the invention, and it is to be understood that the invention is not limited to the specific forms disclosed, but covers all modifications, changes and alternative constructions and methods falling within the scope of the principles taught by the invention.
